A yellowish-brown, distinctively shaped centipede with up to 15 pairs of extremely long legs. As with all other centipedes, there is only one pair of legs per leg-bearing body segment. The legs of house centipedes are barbed to help hold prey. The species we most commonly see has three dark stripes running along the top of the body. Unlike many other centipedes commonly encountered, house centipedes are not flattened top to bottom, and they can run startlingly quickly.
